Description

Technical Field

[0001] The utility model relates to the technical field of display equipment, in particular to a display device. Background Art

[0002] As a major accessory of current display devices such as TV products, the base has been shipped as a standard feature in recent years. However, once the user chooses to wall-mount the product, the base is mostly discarded or left idle. Utility Model Content

[0003] The utility model discloses a display device, which is used to avoid the situation that a base is idle when the whole machine is wall-mounted.

[0004] In order to achieve the above object, the utility model provides the following technical solutions:

[0005] A display device, comprising: a housing and a movable base, wherein the movable base comprises a telescopic rod group and a base, and the base is rotatably mounted on the housing through the telescopic rod group;

[0006] The base has a first state and a second state relative to the housing. When the base is in the first state, the length direction of the base is parallel to the display surface of the display device; when the base is in the second state, the length direction of the base is perpendicular to the display surface of the display device;

[0007] The telescopic rod set is used to drive the base to reciprocate along a first direction, and to drive the base to rotate around the first direction, so that the base switches between the second state and the first state.

[0008] The above-mentioned display device includes a shell and a movable base, and the movable base can be switched between a first state and a second state relative to the shell. When the base is not needed, such as when the entire display device is fixed by wall hanging, the base can directly store the movable base in the display device and switch the base to the first state; when the base is needed, such as when the base needs to support the entire display device or when other external devices such as an echo wall need to be additionally hung, the movable base can be switched to the second state. Specifically, the switching of the base state is achieved by a telescopic rod group. The base is rotatably mounted on the shell through the telescopic rod group, and can be rotated relative to the shell around a first direction such as a vertical direction. The rotating base can adjust its length direction, for example, the length direction of the base is adjusted to be parallel to the display surface of the display device or perpendicular to the display surface to adapt to different usage scenarios. The telescopic rod group realizes the linear movement of the base relative to the shell along the first direction through its own telescopic movement. For example, for the sake of aesthetics, the length of the telescopic rod group along the first direction can be shortened so that the base is hidden behind the display device. The display device provided in the embodiment of the utility model has a base that can be used normally as the base of the display device, and can also be hidden inside the shell when the user chooses a wall-mounted solution, or can be used as a bracket for other external devices such as a soundbar, thereby avoiding the situation where the base is idle when the whole machine is wall-mounted.

DETAILED DESCRIPTION

[0056] First, let me introduce the application scenario of this application: the base is the main accessory of current display devices such as TV products. In recent years, it has been shipped as a standard configuration for overseas models. However, once the user chooses to wall-mount the base, the base is mostly discarded or idle. Considering that overseas users, especially those in the European and American markets, have high demands for sound quality, most TVs are used with bar-shaped echo walls, and the echo wall still needs to be placed separately on the TV cabinet or hung on the wall separately.

[0057] Based on the above application scenarios, an embodiment of the present application provides a display device, the base of which can be used normally as a TV base, and can also be used as a bracket for a strip sound bar when the user chooses a wall-mounted solution.

[0058] The following will combine the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" refers to two or more than two.

[0059] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, "plurality" means two or more.

[0060] like Figure 1-Figure 6 As shown, the embodiment of the utility model provides a display device 100, including: a housing 110 and a movable base, the movable base includes a telescopic rod group 120 and a base 130, and the base 130 is rotatably mounted on the housing 110 through the telescopic rod group 120;

[0061] The base 130 has a first state and a second state relative to the housing 110. When the base 130 is in the first state, the length direction of the base 130 is parallel to the display surface A1 of the display device 100; when the base 130 is in the second state, the length direction of the base 130 is perpendicular to the display surface A1 of the display device 100.

[0062] The telescopic rod set 120 is used to drive the base 130 to reciprocate along the first direction, and is used to drive the base 130 to rotate around the first direction, so that the base 130 switches between the second state and the first state.

[0063] The above-mentioned display device 100 includes a shell 110 and a movable base. The movable base can be switched between a first state and a second state relative to the shell 110. When the base 130 is not needed, such as when the entire display device 100 is fixed by wall mounting, the base 130 can directly store the movable base in the display device 100 and switch the base 130 to the first state; when the base 130 needs to be used, such as when the base 130 needs to support the entire display device 100 or other external devices such as a sound bar 300 need to be additionally hung, the movable base can be switched to the second state.

[0064] Specifically, the switching of the state of the base 130 is achieved through the telescopic rod group 120. The base 130 is rotatably mounted on the housing 110 through the telescopic rod group 120, and can be rotated relative to the housing 110 around a first direction, such as a vertical direction. The rotating base 130 can adjust its length direction, for example, the length direction of the base 130 can be adjusted to be parallel to the display surface A1 of the display device 100 or perpendicular to the display surface A1 to adapt to different usage scenarios. The telescopic rod group 120 realizes the linear movement of the base 130 relative to the housing 110 along the first direction through its own telescopic movement. For example, for the sake of aesthetics, the length of the telescopic rod group 120 along the first direction can be shortened so that the base 130 is hidden behind the display device 100.

[0065] The display device provided in the embodiment of the utility model has a base 130 which can be normally used as the base 130 of the display device, or can be hidden inside the shell 110 when the user chooses a wall-mounted solution, or can be used as a bracket for other external devices such as a strip sound bar, thereby avoiding the situation where the base 130 is idle when the whole machine is wall-mounted.

[0066] In some embodiments, the telescopic rod assembly 120 includes a first connecting rod 121, a second connecting rod 122, a third connecting rod 123 and a fourth connecting rod 124, and the first end of the first connecting rod 121 is hinged to the first end of the third connecting rod 123 to form the first end of the telescopic rod assembly 120;

[0067] The second end of the first connecting rod 121 is hinged to the first end of the second connecting rod 122, and the second end of the third connecting rod 123 is hinged to the first end of the fourth connecting rod 124;

[0068] The second end of the second connecting rod 122 is connected to the second end of the fourth connecting rod 124 to form the second end of the telescopic rod assembly 120;

[0069] The first end of the telescopic rod group 120 is rotatably connected to the housing 110, and the second end of the telescopic rod group 120 is connected to the base 130;

[0070] When the base 130 is in the second state, the first connecting rod 121 , the second connecting rod 122 , the third connecting rod 123 and the fourth connecting rod 124 are relatively fixed by a plurality of locking members 129 .

[0071] like Figure 7-Figure 9 As shown, the first link 121, the second link 122, the third link 123 and the fourth link 124 are connected to form a four-link structure, the first link 121 and the second link 122 are connected by a first rotating shaft 125, the second link 122 and the fourth link 124 are connected by a second rotating shaft 126, the first link 121 and the second link 122 are connected by a third rotating shaft 127, and the third link 123 and the fourth link 124 are connected by a fourth rotating shaft 128. The length of the entire telescopic rod group 120 along the first direction is changed by changing the four-link structure, thereby adjusting the relative position of the base 130 and the display device.

[0072] When the base 130 is in the second state, in order to ensure that the base 130 has a certain supporting force, the state of the four-bar structure needs to remain stable. Multiple locking members can be used to lock the four connecting rods. The locking members can be screws, pins, or detachable support rods.

[0073] For example, Figure 8 and Fig. 9 As shown, the first connecting rod 121 and the third connecting rod 123 are locked by a locking member, such as a first screw Z1 that sequentially penetrates the first locking hole a1 of the first connecting rod 121 and the first locking hole a2 of the second connecting rod 122 to prevent the first connecting rod 121 and the third connecting rod 123 from rotating relative to each other around the first rotating shaft 125; the first connecting rod 121 and the second connecting rod 122 are locked by another locking member, such as a second screw Z2 that sequentially penetrates the second locking hole b1 of the first connecting rod 121 and the second locking hole b2 of the second connecting rod 122 to prevent the first connecting rod 121 and the second connecting rod 122 from rotating relative to each other around the third rotating shaft 127 ; The third connecting rod 123 and the fourth connecting rod 124 are locked by another locking member, such as by a third screw Z3 that sequentially penetrates the third locking hole c1 of the third connecting rod 123 and the third locking hole c2 on the fourth connecting rod 124 to avoid the relative rotation between the third connecting rod 123 and the fourth connecting rod 124 around the fourth rotation axis 128; the second connecting rod 122 and the fourth connecting rod 124 are locked by another locking member, such as by a fourth screw Z4 that sequentially penetrates the fourth locking hole d1 of the second connecting rod 122 and the fourth locking hole d2 on the fourth connecting rod 124 to avoid the relative rotation between the second connecting rod 122 and the fourth connecting rod 124 around the second rotation axis 126.

[0074] In some embodiments, Figure 8 and Fig. 9 As shown, and refer to Figure 7The first connecting rod 121 and the third connecting rod 123 are symmetrically arranged along the first direction, and the second connecting rod 122 and the fourth connecting rod 124 are symmetrically arranged along the first direction. That is to say, the first connecting rod 121 and the third connecting rod 123 can adopt rods of the same length size, and the second connecting rod 122 and the fourth connecting rod 124 can adopt rods of the same length size. Further, the first connecting rod 121 and the third connecting rod 123 can be the same rod, and the second connecting rod 122 and the fourth connecting rod 124 can be the same connecting rod, which is convenient for processing and installation.

[0075] When the base 130 is in the second state, the telescopic rod set 120 is configured as a rod-shaped structure extending along the first direction. The second screw Z2 and the third screw Z3 can be the same screw, that is, the screw sequentially passes through the second locking hole b1 of the first connecting rod 121, the second locking hole b2 on the second connecting rod 122, the third locking hole c1 of the third connecting rod 123, and the third locking hole c2 on the fourth connecting rod 124, which can simplify the structure and facilitate installation and fixation.

[0076] When the telescopic rod set 120 forms a rod-shaped structure extending in the first direction, the length of the entire structure is the longest, which can provide a stable supporting force, and each connecting rod is evenly stressed, thereby extending the service life of the telescopic rod set 120. On this basis, when the base 130 is in the first state, the entire structure of the telescopic rod set 120 is small in size and convenient for storage.

[0077] In some embodiments, the telescopic rod set 120 can be directly connected and rotatably assembled to the housing 110, such as an integrally formed shaft seat body is provided on the housing 110, the shaft eye of the shaft seat body extends in the first direction and is penetrated through the telescopic rod set 120, so that the telescopic rod set 120 can rotate relative to the shaft seat body around the shaft. The movable base also includes an adapter assembly 140, and the telescopic rod set 120 can also be indirectly connected and rotatably assembled to the housing 110, and the telescopic rod set 120 can be rotatably assembled to the adapter assembly 140.

[0078] like Figure 8 and Fig. 9 As shown, the adapter assembly 140 includes an adapter bracket 141, a rotating joint 142, an adapter shaft 143 and a connecting joint 144; the adapter bracket 141 is fixed to the shell 110, the rotating joint 142 is rotatably connected to the adapter bracket 141 through the adapter shaft 143, and the axial direction of the adapter shaft 143 is parallel to the first direction; the first end of the telescopic rod group 120 is connected to the rotating joint 142 through the connecting joint 144.

[0079] Reference Figure 5 and Figure 6, the adapter bracket 141 is fixed to the housing 110, the rotary joint 142 is rotatably connected to the adapter bracket 141 through the adapter shaft 143, and the telescopic rod set 120 is fixed to the rotary joint 142 through the connecting joint 144. Exemplarily, the adapter bracket 141 can be fixed to the housing 110 by threading, bonding or clamping, and the connecting joint 144 is fixed to the rotary joint 142 by threading, bonding or clamping, and can rotate around the adapter shaft 143 relative to the housing 110, thereby driving the entire telescopic rod set 120 to rotate around the adapter shaft 143 relative to the housing 110.

[0080] When the base 130 is in the first state, the folding plane of the telescopic rod set 120 and the length direction of the base 130 are parallel to the display surface A1 of the display device, which can avoid increasing the thickness of the entire display device.

[0081] When the base 130 is in the second state, the folding plane of the telescopic rod group 120 and the length direction of the base 130 are perpendicular to the display surface A1 of the display device. At this time, when observing the display device along the first direction, a part of the base 130 is located in front of the display device, and the other part is located behind the display device, which can provide stable support for the entire display device.

[0082] like Fig.10 and Fig.11 As shown, the adapter bracket 141 has three mounting holes e, which are arranged in a triangle. Mounting parts such as screws can pass through the mounting holes e to install the adapter bracket 141. The adapter bracket 141 is also provided with a mounting seat for mounting the rotary joint 142. The mounting seat includes two mounting protrusions 141a arranged at intervals. A mounting groove 141b for accommodating the rotary joint 142 is formed between the two mounting protrusions 141a. At the same time, the two mounting protrusions 141a have axial holes f with overlapping axes, and the rotary joint 142 has an axial hole g, as shown in FIG. Fig.12 and Fig.13 When the rotary joint 142 is inserted into the mounting groove 141b, the adapter shaft 143 passes through the first shaft hole f, the shaft hole g on the rotary joint 142 and the other shaft hole f in sequence.

[0083] like Figure 11-13 As shown, the mounting seat is formed on one side surface of the adapter bracket 141, and one side of the rotating joint 142 has an arc surface 142a, and the other side opposite to it has a flat surface 142b, and the arc surface 142a faces one side of the mounting seat to avoid motion interference, referring to Fig.10 Plane 142b has a connection hole h for mounting the connection joint 144 to ensure the reliability of the connection, refer to Figure 8 The whole structure enables the rotary joint 142 to rotate around the adapter shaft 143 within a range of 180°.

[0084] like Fig.14 As shown, the connection joint 144 has a connection hole i, and the connection joint 144 can be connected to the rotating joint 142 by a screw, and the screw passes through the connection hole i and is connected to the connection hole h on the rotating joint 142, as shown in FIG. Figure 8 and Fig. 9 The connection joint 144 and the rotary joint 142 are in surface contact, and the connection is reliable and stable.

[0085] In some embodiments, the first connecting rod 121 and the third connecting rod 123 are rotatably connected to the connecting joint 144 via the first rotating shaft 125; the first end of the first connecting rod 121 and / or the first end of the third connecting rod 123 are provided with an arc-shaped notch, and the connecting joint 144 is provided with a limiting protrusion that cooperates with the arc-shaped notch, which is used to limit the extreme position of the rotation of the first connecting rod 121 and / or the third connecting rod 123 relative to the connecting joint 144.

[0086] One possible way to achieve this is as follows: Fig.14 As shown, a mounting seat for mounting the telescopic rod set 120 is provided at one end of the connecting joint 144 away from the connecting hole i, and the mounting seat includes three mounting protrusions 144a arranged at intervals, and a mounting groove 144b for accommodating the first connecting rod 121 or the third connecting rod 123 is formed between two adjacent mounting protrusions 144a, and at the same time, the three mounting protrusions 144a have axial holes j with coinciding axes, the first connecting rod 121 has an axial hole k, and the third connecting rod 123 has an axial hole l, and the first connecting rod 121 and the third connecting rod 123 have the same structure, as shown in FIG. Fig.15 When the first connecting rod 121 is inserted into one of the mounting grooves 144b and the third connecting rod 123 is inserted into the other mounting groove 144b, the first rotating shaft 125 sequentially passes through the first shaft hole j, the shaft hole k on the first connecting rod 121, the second shaft hole j, the shaft hole l on the third connecting rod 123 and the third shaft hole j, thereby realizing the rotation connection between the first connecting rod 121, the third connecting rod 123 and the connecting joint 144.

[0087] like Fig.14 and Fig.15 As shown, the first end of the first connecting rod 121 and the first end of the third connecting rod 123 are both provided with an arc-shaped notch, and a limiting protrusion 144c is provided in each mounting groove 144b of the connecting joint 144. The arc-shaped notch 121a on the first connecting rod 121 cooperates with the limiting protrusion 144c in one mounting groove 144b to limit the rotation range of the first connecting rod 121; the arc-shaped notch 123a on the third connecting rod 123 cooperates with the limiting protrusion 144c in another mounting groove 144b to limit the rotation range of the third connecting rod 123.

[0088] It is understandable that the arc-shaped notch can be formed integrally with the first connecting rod 121 or the third connecting rod 123, or the arc-shaped notch can be formed by removing a portion of the first connecting rod 121 or the third connecting rod 123. The area of ​​the arc-shaped notch is the range in which the first connecting rod 121 or the third connecting rod 123 rotates.

[0089] Continue to refer to Figure 7 The first connecting rod 121 and the third connecting rod 123 have the same structure, but are installed in opposite directions on the connecting joint 144, so that the arc notch 121a on the first connecting rod 121 and the arc notch 123a on the third connecting rod 123 are in opposite directions, indicating that the first connecting rod 121 and the third connecting rod 123 can rotate in opposite directions.

[0090] like Fig.15 As shown, the first connecting rod 121 is provided with a mounting seat for mounting the second connecting rod 122 at one end away from the shaft hole k, and the mounting seat includes two mounting protrusions 121b arranged at intervals, and a mounting groove 121c for accommodating the second connecting rod 122 is formed between the two mounting protrusions 121b. At the same time, the two mounting protrusions 121b have shaft holes m with overlapping axes, and the second connecting rod 122 has a shaft hole o. Fig.16 When the second connecting rod 122 is inserted into the mounting groove 121b, the third rotating shaft 127 passes through the first shaft hole m, the shaft hole o on the rotating joint 142 and another shaft hole m in sequence.

[0091] like Fig.15 As shown, the end of the third connecting rod 123 away from the shaft hole l is provided with a mounting seat for mounting the fourth connecting rod 124, and the mounting seat includes two mounting protrusions 123b arranged at intervals, and a mounting groove 123c for accommodating the fourth connecting rod 124 is formed between the two mounting protrusions 123b. At the same time, the two mounting protrusions 123b have shaft holes n with overlapping axes, and the fourth connecting rod 124 has a shaft hole p. Fig.16 When the second connecting rod 122 is inserted into the mounting groove 123b, the fourth rotating shaft 128 passes through the first shaft hole n, the shaft hole p on the rotating joint 142 and another shaft hole n in sequence.

[0092] In some embodiments, the second connecting rod 122 and the fourth connecting rod 124 are rotatably connected to the connecting portion 131 on the base 130 via the second rotating shaft 126; the second end of the second connecting rod 122 and / or the second end of the fourth connecting rod 124 are provided with an arc-shaped notch, and the connecting portion 131 is provided with a limiting protrusion that cooperates with the arc-shaped notch, which is used to limit the extreme position of the rotation of the second connecting rod 122 and / or the fourth connecting rod 124 relative to the connecting portion 131.

[0093] One possible way to achieve this is as follows: Fig.17As shown, the connecting portion 131 of the base 130 includes three installation protrusions 131a arranged at intervals, and a mounting groove 131b for accommodating the second connecting rod 122 or the fourth connecting rod 124 is formed between two adjacent installation protrusions 131a. At the same time, the three installation protrusions 131a have shaft holes s with overlapping axes, the second connecting rod 122 has a shaft hole q, and the fourth connecting rod 124 has a shaft hole r. The second connecting rod 122 and the fourth connecting rod 124 have the same structure, as shown in FIG. Fig.16 When the second connecting rod 122 is inserted into one of the mounting grooves 131b and the fourth connecting rod 124 is inserted into the other mounting groove 131b, the second rotating shaft 126 sequentially passes through the first shaft hole s, the shaft hole q on the second connecting rod 122, the second shaft hole s, the shaft hole r on the fourth connecting rod 124 and the third shaft hole s, thereby realizing the rotation connection between the second connecting rod 122, the fourth connecting rod 124 and the connecting portion 131 of the base 130.

[0094] like Fig.16 and Fig.17 As shown, the second end of the second connecting rod 122 and the second end of the fourth connecting rod 124 are both provided with an arc-shaped notch, and a limiting protrusion 131c is provided in each mounting groove 131b of the connecting portion 131. The arc-shaped notch 122a on the second connecting rod 122 cooperates with the limiting protrusion 131c in one mounting groove 131b to limit the rotation range of the second connecting rod 122; the arc-shaped notch 124a on the fourth connecting rod 124 cooperates with the limiting protrusion 131c in another mounting groove 131b to limit the rotation range of the fourth connecting rod 124.

[0095] It is understandable that the arc-shaped notch can be formed integrally with the second connecting rod 122 or the fourth connecting rod 124, or the arc-shaped notch can be formed by removing a portion of the second connecting rod 122 or the fourth connecting rod 124. The area of ​​the arc-shaped notch is the range in which the second connecting rod 122 or the fourth connecting rod 124 rotates.

[0096] Continue to refer to Fig.16 The second connecting rod 122 and the fourth connecting rod 124 have the same structure, but are installed in opposite directions on the connecting portion 131, so that the arc notch 122a on the second connecting rod 122 and the arc notch 124a on the fourth connecting rod 124 are in opposite directions, indicating that the second connecting rod 122 and the fourth connecting rod 124 can rotate in opposite directions. Fig.18 and Fig.19 shown.

[0097] When the base 130 is in the second state: the first connecting rod 121 and the third connecting rod 123 are locked with the first screw Z1, and due to the limiting effect of the upper limit protrusion 144c of the connecting joint 144, the arc notch 121a of the first connecting rod 121 and the arc notch 123a of the third connecting rod 123 are respectively in contact with the limiting protrusion 144c, and the rotation directions of the first connecting rod 121 and the third connecting rod 123 are opposite, so that the interlocking of the first connecting rod 121 and the third connecting rod 123 is achieved; when the first connecting rod 121 is connected with the second connecting rod 122 and the third connecting rod 123 and the fourth connecting rod 124, the first connecting rod 121 and the third connecting rod 123 are connected with the first connecting rod 121 and the third connecting rod 123. The first link 121 and the second link 122, and the third link 123 and the fourth link 124 are locked with screws to prohibit relative rotation; similarly, the second link 122 and the fourth link 124 are locked with the fourth screw Z4, and due to the limiting effect of the limiting protrusion 131c on the base 130, the arcuate notch 122a of the second link 122 and the arcuate notch 124a of the fourth link 124 are in contact with the limiting protrusion 131c to the bottom, respectively, and the rotation directions of the second link 122 and the fourth link 124 are opposite, thereby realizing the interlocking of the second link 122 and the fourth link 124.

[0098] The movable base provided in this embodiment can move along a first direction relative to the shell 110 of the display device. When the display device needs to be wall-mounted, the base 130 can be driven to move to the area covered by the shell 110 by controlling the telescopic rod group 120. Specifically, it can be moved to the back side of the shell 110, that is, the side of the display device away from the display surface A1, and does not exceed the position of the edge of the shell 110; or it can be moved to the inside of the shell 110 to achieve the storage of the base 130.

[0099] Similarly, when the display device needs to be supported by the base 130 or the base 130 is used as a hanger for external equipment, the telescopic rod group 120 can be first rotated 90° to the left or right around the adapter shaft 143, and then the base 130 can be driven to move outward along the first direction, specifically extending outward from the back side of the shell 110, or extending outward from the inside of the shell 110, so as to use the extended base 130 to support the display device.

[0100] The material of the four connecting rods in the movable base may be No. 12 aluminum material (ADC12), and the material of the base 130 may be aluminum profile AL6063.

[0101] In some embodiments, the housing 110 has a receiving cavity, and a avoidance passage communicating with the receiving cavity is provided on the housing 110, and the base 130 enters the receiving cavity or extends out of the housing 110 through the avoidance passage. Based on the above arrangement, when the display device is fixed in a wall-mounted manner, the base 130 that exceeds the edge of the housing 110 can be prevented from interfering with and affecting the user's perception.

[0102] like Fig. 20As shown, there are two movable bases, and the two movable bases are spaced apart along the length direction of the display device 100 , which can provide stable support on the basis of the small-sized base 130 , and can be conveniently stored inside the shell 110 without affecting the supporting function of the base 130 .

[0103] In some embodiments, the shell 110 includes a back panel 111, a main rear shell 112 and a sub-rear shell 113; the base 130 is rotatably mounted on the back panel 111 through the telescopic rod group 120, the sub-rear shell 113 is detachably connected to the main rear shell 112, and the sub-rear shell 113 is configured to form a storage space for accommodating the movable base together with the back panel 111 and the main rear shell 112 when the base 130 is in a first state, and the sub-rear shell 113 is also configured to allow the telescopic rod group 120 to pass through when the base 130 is in a second state.

Fig.24 As shown, the secondary rear shell 113 is an L-shaped structure, and has an avoidance opening 113a on the secondary rear shell 113, which avoids the telescopic rod group 120 when the base 130 is in the second state. The setting of the secondary rear shell 113 can not only meet the switching of the two states of the base 130, but also achieve a dust-proof effect to a certain extent with a small opening size.

[0105] In some embodiments, Fig.24 As shown, a protrusion 113b is provided on the side of the secondary rear shell 113 facing the back plate 111, and the protrusion 113b is configured to abut against the rotating joint 142 when the base 130 is in the second state. Exemplarily, the protrusion 113b is a conical column, and the top surface of the conical column is a plane; when the base 130 is in the second state, the secondary rear shell 113 is assembled on the main rear shell 112, and at this time, the conical column on the secondary rear shell 113 is pressed against the rotating joint 142, limiting the rotation of the rotating joint 142.

[0106] A plurality of buckles 113 c are disposed on the side of the auxiliary rear shell 113 facing the main rear shell 112 , and the auxiliary rear shell 113 can be buckled onto the main rear shell 112 through the buckles 113 c.

[0107] In some embodiments, the display device 100 further includes a double-sided adhesive tape 200, which is configured to be bonded to the base 130 to bond an external device, such as Fig.25 The length of the double-sided adhesive tape 200 can be equal to the length of the base 130, and the width can be smaller than the width of the base 130. Of course, the length of the double-sided adhesive tape 200 can be cut as needed. For example, the double-sided adhesive tape 200 can be a foam double-sided adhesive tape.

[0108] like Fig.26 As shown, the double-sided tape 200 includes a substrate 210, an adhesive layer 220 and a release layer 230. The substrate 210 may be EPDM (Ethylene Propylene Diene Monomer), the substrate 210 includes a first surface and a second surface relative to each other, the first surface and the second surface are both provided with an adhesive layer 220, the adhesive of the adhesive layer 220 may be acrylic, the release layer 230 is located on the side of each adhesive layer 220 facing away from the substrate 210, and the release layer 230 may be PEK (polyaryletheretherketone) release paper.

[0109] like Fig. 27 and Fig.28 As shown, the base 130 provided in this embodiment can be used as a bracket for the strip-shaped echo bar 300. When the base 130 is used as a bracket for the echo bar 300, the user can tear off the release paper on the foam double-sided adhesive tape and paste a foam double-sided adhesive tape on the left and right bases 130 respectively; the foam double-sided adhesive tape is used to paste and fix the echo bar 300; the length of the foam double-sided adhesive tape can be the same as the length of the base 130, and the width can be less than the width of the base 130. The user can cut the length of the foam double-sided adhesive tape according to the width of the echo bar 300 to ensure the connection reliability.

[0110] In summary: in the display device 100 provided in the embodiment of the present application, the base 130 can be used normally as the base 130 of the display device 100 such as a TV, and the base 130 can be installed on the display device 100 and placed on a cabinet for use; the base 130 can also be hidden in the back shell when the user chooses a wall-mounted solution; or it can be used as a hanger for the strip-shaped echo wall 300, and the user can install the base 130 on the display device 100 and then install the display device 100 on the wall through wall-mounting; the double-sided tape 200 is cut according to the width of the echo wall 300 and pasted on the base 130, and then the echo wall 300 is pasted on the double-sided tape 200 to avoid the situation where the base 130 is idle when the whole machine is wall-mounted. The movable base can be applied to a small-sized and light-weight display device 100.
